If you care about standards then I think you need to be a little more
precise.

ISO 8601:2000 recognizes yymmdd as a "truncated representation" of a date,
and allows its use only "by mutual agreement of the partners in information
interchange". The standard defines two formats for the "complete
representation" of a "calendar date", namely the "basic format" yyyymmdd,
and the "extended format" yyyy-mm-dd. In XML documents, the extended format
is preferable, because it is the one that XML Schema has adopted. But the
basic format can be useful on occasions because it allows "<" and ">"
comparisons in XPath 1.0 expressions, treating the date as a number.
